SPECIFICATION forming part of Letters Patent No. 628,911, dated July 18, 1899.

Application filed January 7, 1897. $erial No. 618,375. (No model.)

To all whom it may concern.-

Be it known that I, lVALLACE S. AYRES, a citizen of the United States, and a resident of Hazleton, in the county of Luzerne and State of Pennsylvania, have invented a new and useful I-Iitching-Staple for Cars, of which the following is a specification.

My invention relates to improvements in hitching-staples for mine and other cars, which are attached to a cross-beam at either end of the car; and the objects of my improvements are, first, to so construct the staple that all indirect pulls upon it, such as occur when the car passes from a level to an inclined plane or when it passes over the summitof the plane, will not bend it; second, to use a minimum of metal in its construction; third, to so construct it that it will in no way interfere with the coupling and uncoupling of the cars, and, fourth, to somake it that it may be applied without any alteration in the cars. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a rear end view of the hitchingstaple; Fig. 2, a side view showing the staple as attached to the cross-beam of car; Fig. 3, a front end View, and Fig. 4 a plan view of the entire hitching-staple removed from the cross-beam.

Similar letters refer to the same parts through the several views.

The round part A A constitutes the main body of the hitching-staple. The nuts B B secure it to the cross-beam G G" of the car. It can also be secured to the beam by the use of slots and keys instead of nuts or by any of the devices now in common use; The wings O O are a part of the hitching-staple and are formed with the round body by drop-forging and without any Welding together of the parts. These wings can be made to touch the washerplate D D at various points across its entire Width, but are preferably provided with projections F F, so as to insure a perfect contact with the washer-plate D D at its outer edge, thusenabling the staple to resist any bending action that may occur from an oblique pull up or down, and also to insure the nuts B B drawing the staple against the washer-plate D D and beam G G in the firmest manner possible. The washer E is extended on either side of the hitching-staple and connects with the side beams of the car in the usual way by bolts. Economy of material is accomplished from the fact that the wings are made only thick enough to resist the bending action for i a given angle of oblique pull, while the body of the staple is made sufficiently large to resist the direct pull.

The wings O C are simply added to any old form of staple and are so placed on each side of the center of the loop as to in no way interfere with the coupling and uncoupling of the cars. By thus adding these brace-wings O O to any old form of staple my invention can be applied to any cars now in use without any alterations in the cars by simply removin g the old form of staple.

I prefer to carry out the features of my invention as shown in the accompanying drawings, although the wings can be modified in shape and location to suitdifferent constructions of cars and different methods of fastening the staple to the cross-beam.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A hitching staple having one or more brace wings or projections for bracing the body of the staple, substantially as set forth.

2. A hitching-staple having one or more brace wings or projections integral with the body of the staple, substantially as set forth.

3. A hitchingstaple having brace wingsintegral with the staple and situated on opposite sides of each fork of the staple, substantially as set forth.

i. A hitching-staple having Wings 0 0 provided with the projections F F, substantially as shown and described.

5. The combination of a hitching-staple, having the wings O Cand the projections F F, with the Washer-plate DD and cross-beam G G, substantially as shown and for the pur
